No one knows exactly how many disabled people there are in the world, but estimates suggest the figure is over 450 million. The number of disabled people in India alone is probably more than double the total population of Canada. In the United Kingdom, about one in ten people have some disability. Disability is not just something that happens to other people: as get older, many of us will become less mobile, hard of hearing or have failing eyesight. Disablement can take many forms and occur at any time of life. Some people are born with disabilities. Many others become disabled as they get older. There are many progressive disabling diseases. The longer time goes on, the worse they become. Some people are disabled in accidents. Many others may have a period of disability in the form of a mental illness. All are affected by people’s attitude towards them. Disabled people face many physical barriers. Next time you go shopping or to work or visit friends, imagine how you would manage if you could not get up steps, or on to buses and trains. How would you cope if you could not see where you were going or could not hear the traffic But there are other barriers: prejudice can be even harder to break down and ignorance inevitably represents by far the greatest barrier of all. It is almost impossible for the able-bodied to fully appreciate what the severely disabled go through, so it is important to draw attention to these barriers and sow that it is the individual person and their ability, not their disability, which counts. The key word in Paragraph 4 is ______.

A. disability
B. ignorance
C. prejudice
D. barriers

"I have great confidence that by the end of the decade we’ll know in vast detail how cancer cells arise," says microbiologist Robert Weinberg, an expert on cancer, "But," he cautions, "some people have the idea that once one understands the causes, the cure will rapidly follow. Consider Pasteur. He discovered the causes of many kinds of infections, but it was fifty or sixty years before cures were available." This year, 50 percent of the 910 000 people who suffer from cancer will survive at least five years. In the year 2000, the National Cancer Institute estimates, that figure will be 75 percent. For some skin cancers, the five-year survival rate is as high as 90 percent. But other survival statistic(统计)rate still discouraging-13 percent for lung cancer, and 2 percent for cancer of the pancreas(胰腺). With as many as 120 varieties in existence, discovering how cancer works is not easy. The researchers made great progress in the early 1970s, when they discovered that oncogenes, which are cancer-causing genes(基因), are inactive in normal ceils. Anything from cosmic rays to radiation to diet may activate a dormant oncogene, but how remains unknown. If several oncogenes are driven into action, the cell, unable to turn them off, becomes cancerous. The exact mechanisms involved are still mysterious, but the likelihood that many cancers are initiated at the level of genes suggest that we will never prevent all cancers. "Changes are a normal part of the evolutionary process," says oneologist William Hayward. Environmental factors can never be totally eliminated; as Hayward points out, "We can’t prepare a medicine against cosmic rays." The prospects for cure, though still distant, are brighter. "First, we need to understand how the normal cell controls itself. Second, we have to determine whether there are a limited number of genes in cells, which are always responsible for at least part of the trouble. If we can understand how cancer works, we can counteract its action.\ The word "dormant" in the third paragraph most probably means ______.

A. dead
B. ever-present
C. inactive
D. potential

1. Humans not only love eating ice cream, they enjoy feeding it to their pets(宠物). Market studies show that two thirds of all dog owners give ice cream ot their dogs. Unfortunately, says William Tyznik, an expert on animal nutrition(营养)at Ohio State University, ice cream is not good for dogs. "It has milk sugar in it, "he says," which dogs cannot digest very well." 2. Bothered by that knowledge but aware of the desire of dog owners to please their companions, Tyznik invented a new frozen treat for dogs that, he says, is more nutritious than ice cream--and as much fun to eat. The product, called Frosty Paws, is made of a liquid by-product(副产品)of cheese and milk with the sugar removed. Frosty Paws also contains refined soy flour, water, vegetable oil, vitamins and minerals. It took Tyznik, who has also invented a horse feed (called Tizwhiz) and another dog food (named Tizbits), three years to perfect the Frosty Paws formulas, and two attempts to commercialise it. After losing $ 25,000 trying to market the invention himself, Tyznik sold the rights to Associated Ice Cream of Westerville, Ohio, which makes the product and packages it in cups. 3. Tyznik claims that Frosty Paws has been tested extensively and that "dogs love it". Of 1,400 dogs that have been offered the product, he says, 89 percent took it on the first try. Three out of four preferred it to Milk-Bone or sausages. The product, which will be available in the ice-cream section of supermarkets, comes in packs of three or four cups, costing between $ 1.79. 4. What would happen if a human should mistake Frosty Paws for real ice cream Nothing, says Tyznik. It’s harmless, but frankly, he says, it won’t taste very good. Para 3 ______.
